Abstract
It is a common conception that entitlement is increasing among younger generations over time. However, although there is some evidence for this trend, other findings are less conclusive. The current research investigated change in psychological entitlement across the adult lifespan for men and women (ages 19-74), using six annual waves of data (2009-2014) from the New Zealand Attitudes and Values Study (N = 10,412). We employed Cohort-Sequential Latent Growth Modeling to assess mean-level change in entitlement. Entitlement was found to be generally unchanging over time for both men and women, with only those aged 65 and above showing increasing entitlement. Entitlement showed a steady downward trend across age. These findings from a large national probability sample suggest that change in entitlement may follow a decreasing developmental trend across the lifespan. In New Zealand, at least, there is no evidence for a narcissism epidemic.
Both the public discourse and psychological literature are concerned with the current “narcissism epidemic” or “culture of entitlement”—that is, the idea that narcissism and entitlement are on the rise (Stein, 2013; Twenge, 2013). In particular, “millennials” (born between 1982 and 2002) are believed to be more narcissistic and entitled than previous generations, due to recent cultural shifts toward individualism and selfishness (Stein, 2013; Twenge, 2006), producing unrealistically positive self-views associated with grandiose behavior, aggression, and exploitativeness (Krizan & Herlache, 2017). However, providing data to support these claims is challenging, as developmental trends (levels of entitlement changing as people age and mature) and societal trends (shifts in culture over time and differences between generations) are likely to be occurring at the same time. In addition, any changes are likely to differ from context to context, and yet research has largely been confined to the United States. In the current research, we analyze a representative sample of New Zealanders and employ Cohort-Sequential Latent Growth Models (LGMs) to present new data on this issue, tracking change in psychological entitlement across 6 years over the entire adult lifespan for men and women.
Narcissism and Entitlement Over Time
Efforts to untangle cohort effects from developmental effects and examine change in narcissism across generations have been made by collecting multiple cross-sectional samples of North American college students across several decades and comparing their narcissism scores (see Trzesniewski & Donnellan, 2010; Twenge, 2013 for a review). However, the results from research in this area are conflicting. In the first such cross-temporal meta-analysis, Twenge, Konrath, Foster, Campbell, and Bushman (2008) investigated change in narcissism scores (as measured by the Narcissistic Personality Inventory or NPI; Raskin & Terry, 1988) among samples of college students. Results showed that NPI scores increased over time from the 1980’s up to 2006, by approximately a third of a standard deviation. The authors theorized that rising levels of individualism over time have produced a cultural shift where college students today are more entitled than college students at the same age in previous decades and generations (Twenge et al., 2008).
However, when Trzesniewski, Donnellan, and Robins (2008) compared narcissism scores among college and high school students from 1982 to 2007, they concluded that there was no change in NPI scores. This data was subsequently reanalyzed a number of times with various subsamples added or removed, resulting in Twenge and Foster (2008, 2010) concluding that there was an increase in narcissism over time, and Roberts, Edmonds, and Grijalva (2010) and Donnellan, Trzesniewski, and Robins (2009) concluding that there was no change in narcissism over time. In other data, Stewart and Bernhardt (2010) found that narcissism scores among 2004-2008 undergraduate students were higher than scores among undergraduates before 1990, whereas Grijalva et al.’s (2015) meta-analysis found no difference in narcissism scores among undergraduates between 1990 and 2013, and Trzesniewski and Donnellan (2010) found no evidence for increases in egotism, self-enhancement, individualism or self-esteem over time among U.S. high school students (1976-2006).
In sum, there is no definitive pattern of narcissism increasing, or staying the same, over time or across generations. Next, we review the research relating specifically to entitlement, the measure employed in the current research. Psychological entitlement is a core facet of narcissism (Krizan & Herlache, 2017) and represents a global sense that one is entitled to more than others (Campbell, Bonacci, Shelton, Exline, & Bushman, 2004). It is known as the “socially toxic” aspect of narcissism (Ackerman et al., 2011; Trzesniewski et al., 2008); whereas, narcissism as a whole may include some adaptive elements that are associated with positive psychosocial outcomes (Ackerman et al., 2011; Campbell et al., 2007), entitlement is associated with high neuroticism, low agreeableness, higher selfishness and aggression, lower empathy, poorer mental health, and lower self-esteem (Ackerman et al., 2011; Brown, Budzek, & Tamborski, 2009; Campbell et al., 2004; Clarke, Karlov, & Neale, 2015; Grubbs & Exline, 2016). Therefore, psychological entitlement represents a wholly maladaptive trait that taps into the heart of concerns about rising narcissism (cf. Crowe, LoPilato, Campell, & Miller, 2016).
Entitlement can have differing associations to the NPI scale (Ackerman et al., 2011; Brown et al., 2009; Clarke et al., 2015), but in this case seems to show the same pattern of conflicting results across time. Several of the previously reviewed studies (Donnellan et al., 2009; Trzesniewski et al., 2008; Twenge & Foster, 2010) broke the NPI scale down into subscales, including the Entitlement/Exploitativeness subscale. In Trzesniewski et al.’s (2008) study, where no change was found over time with the overall NPI scale, Entitlement/Exploitativeness showed a small increase over time. Yet in other research, Entitlement/Exploitativeness showed no change over time when an increase was found in the NPI scores as a whole (Donnellan et al., 2009; Twenge & Foster, 2010). We interpret these findings with caution as separating the NPI into its subscales lowers its reliability (e.g., Brown et al., 2009), and the Entitlement/Exploitativeness scale and Psychological Entitlement Scale (PES) employed in this study are related but separate measures (Campbell et al., 2004; Grubbs & Exline, 2016)).
Associations With Age
We now turn from cohort research investigating the same age groups across time, to cross-sectional research using samples with wide age ranges at a single time point. Results consistently show that narcissism is negatively associated with age (Foster, Campbell, & Twenge, 2003; Wilson & Sibley, 2011). Research using two large samples of New Zealand adults found that both narcissism and entitlement had negative relationships with age; people in their 20’s scored the highest, but then scores progressively lowered up to age 75 (Wilson & Sibley, 2011). Foster et al. (2003) found similar results in their large, online, cross-cultural sample, with narcissism and entitlement showing negative trends across ages 8 to 83.
These findings fit well with the view of narcissism as a trait that naturally decreases across the lifespan (Kohut, 1971). In fact, multiple theories such as the maturity principle (Caspi, Roberts, & Shiner, 2005) and social investment theory (Roberts & Wood, 2006), suggest a pattern of moving away from entitlement and narcissism as one ages, matures, and increases their commitment to social roles and institutions such as work, marriage, and the community. In Roberts et al.’s (2010) cross-sectional sample, they found that splitting participants into age-dependent roles, such as student or grandparent, magnifies the typically observed negative association between narcissism and age. These results provide strong support for the theory that narcissism is likely to decrease across the lifespan as people take on more mature, interpersonal roles with high levels of commitment.
Gender Differences
Gender has a clear and consistent relationship to narcissism, with men scoring higher than women on measures of both narcissism and entitlement (Foster et al., 2003; Wilson & Sibley, 2011). Grijalva et al.’s (2015) meta-analysis showed that men scored higher on narcissism across 355 studies, and in particular, men scored higher on the entitlement facet of the NPI. However, Grijalva et al. (2015) did not find an interaction between gender and age or gender and time in their meta-analysis, with men simply scoring higher in narcissism across different ages and different generational cohorts. In contrast, cross-sectional data within New Zealand supports the idea that there are gender differences in changes in entitlement, finding that although entitlement was generally negatively associated with age for both men and women, the trend for men was much weaker and lagged behind the trend for women by about 10 to 15 years (Wilson & Sibley, 2011). In addition, in previous research where increases in narcissism have been found, results suggests that only women’s scores are increasing, as they come more in line with men’s higher narcissism scores (Donnellan et al., 2009; Twenge & Foster, 2010; Twenge et al., 2008). Therefore, we aim to examine change in entitlement separately for men and women to avoid such confounds.
Unanswered Questions
Despite the body of research surrounding narcissism and entitlement, there are several issues that remain unaddressed. Firstly, is the question of whether change in narcissism is occurring—or not occurring—among all age groups? Terracciano (2010) and Twenge et al. (2008) both pointed out that, although there is some evidence that societal trends may be affecting levels of entitlement, research has focused exclusively on children, adolescents, and college students. It is difficult to argue that increases in narcissism are occurring only among millennials when there is no similar research available in other age cohorts for comparison. Any increases in narcissism could be the same across all age cohorts, and representative of a larger societal shift. In addition, if there are increases in entitlement over time among young people only, this effect may be a short-lived phenomenon that does not have a long-lasting impact into adulthood as young people navigate a particularly self-focused life stage (Arnett, 2010; Stewart & Bernhardt, 2010; Terracciano, 2010). Change in entitlement may show a completely different trajectory beyond the ages that have been researched so far.
Furthermore, college and high school student samples are not particularly representative of the population and often make use of samples of convenience, so results cannot be readily generalized to other groups (Arnett, 2013; Donnellan et al., 2009; Trzesniewski & Donnellan, 2010; Trzesniewski et al., 2008). Undergraduates now and in previous decades all score above the test norms in narcissism (Stewart & Bernhardt, 2010), so those who attend college are specifically unrepresentative in terms of narcissism. Rising college costs (Davidson, 2015) also mean that each annual sample of college students across the decades may be comprised of wealthier and wealthier segments of the population. Thus, college students are not only unrepresentative of the general population; but they may also be increasingly unrepresentative over time—and increasingly likely to have higher levels of entitlement relative to other young people.
Finally, although discussion of the narcissism epidemic has long since reached New Zealand media (e.g., Remes, 2016), all of the previous research tracking change in narcissism over time has been conducted within the single cultural context of the United States. NPI scores have been found to be higher in the United States than in other locations such as Asia or the Middle East (Foster et al., 2003), suggesting that data from the United States is unlikely to be representative of changes in other countries. Although New Zealand is also a Western country, there are still potential cultural differences in the expression and development of narcissism. New Zealand is a country that emphasizes humility as representative of the national image (Sibley, Hoverd, & Liu, 2011), and Stronge, Cichocka, and Sibley (2016) reported that 91% of their census weighted New Zealand sample had low levels of psychological entitlement. Thus, we have some reason to believe that entitlement levels are lower in New Zealand than in the United States, and that entitlement could develop in different ways as well. The aim of the current research is to address these issues using longitudinal research conducted with a large, representative sample of New Zealanders that is heterogeneous in terms of age and other demographic factors.
Cohort-Sequential LGM
To investigate change in entitlement over the lifespan, we employ Cohort-Sequential LGMs to take into account changes over both time and age (Preacher, Wichman, MacCallum, & Briggs, 2008; Prinzie & Onghena, 2005). We use two different but complementary approaches to do so (see “Method” section for details). First, we estimate a single-group model that estimates change over 6 years across the adult lifespan. If a participant was 18 in 2009, 19 in 2010, and 20 in 2011, their responses inform the estimation of the growth curve at those particular ages. Similarly, a person who was 41, 42, and 43 at the different assessment points would then inform a later portion of the growth curve. With this method, each participant contributes to different parts of the curve across the adult lifespan based on the available data (currently 6 years in the New Zealand Attitudes and Values Study [NZAVS]). Given the size and range of the NZAVS sample, we can estimate changes in psychological entitlement over time across the entire adult lifespan (18-74).
Second, we use a multi-group model to estimate change across 5 years in separate but sequential 5-year birth cohorts. This approach means we can compare change in entitlement across different birth cohorts and see if, for example, younger generations are increasing in entitlement more rapidly or differently to older generations. In addition, the level of entitlement for one age group at their initial point of assessment (2009) will overlap with the estimated level of entitlement for the previous age cohort at their final assessment (2013)—thus, we can we can estimate whether a 25-year old today is more entitled than a 25-year old was 5 years before. Taken together, these approaches allow us not only to observe change as people age, but also assess the magnitude of cohort differences. Naturally, to precisely measure the extent to which change over time is due to aging versus generational differences, many more years of data would be needed—a lifetime’s worth. However, the Cohort-Sequential LGMs offer a method that provides useful information and assists our interpretation of developmental and cohort effects.
Milojev and Sibley (2016) used this technique to investigate change in the Honesty-Humility (H), Emotionality/Neuroticism (E), Extraversion (X), Agreeableness (A), Conscientiousness (C), Openness to Experience (O) (HEXACO) personality traits over time and age. They found that Honesty-Humility (which serves as an approximation of reverse-coded narcissism) showed a steady, positive linear relationship across age, and increases in Honesty-Humility were found within each 5-year birth cohort over a recent 5-year period. This suggests that Honesty-Humility increases as people age, indicating a possible developmental effect. However, there was evidence of cohort differences among younger cohorts, as people at age 34 had higher Honesty-Humility in 2014 than 34-year-olds in 2009—that is, Honest-Humility has increased over time at that age. However, Honesty-Humility includes facets of sincerity and fairness, and so does not provide a pure (reverse-coded) estimate of entitlement (Ashton & Lee, 2007; Milojev & Sibley, 2016). In our reanalysis of this data (Milojev & Sibley, 2016), we use items assessing entitlement only. We also aim to expand on these results by modeling separate LGMs for men and women, as gender differences in narcissism (both cross-sectionally and over time) are well-documented (Foster et al., 2003).
Overview and Guiding Hypotheses
In summary, the association between birth cohorts and entitlement is not particularly clear (e.g., Trzesniewski et al., 2008; Twenge et al., 2008), and the generalizability of previous research is questionable. As much of the previous research has been conducted within the United States, whereas the current research is conducted within New Zealand (a country that emphasizes low entitlement as part of the national image; Sibley, Hoverd, & Liu, 2011), we expect our results to be more in line with those that show no change in entitlement over time. Taken together with the cross-sectional negative association between age and entitlement, which is well supported both empirically and theoretically (Caspi et al., 2005; Wilson & Sibley, 2011), we theorize an overall developmental pattern where entitlement decreases across the lifespan as people age across 6 years, but entitlement does not increase over time over the last 5 years.
In investigating our hypotheses, we would expect to see that the single-group model has a negative slope across age. Because the single-group model incorporates both the cross-sectional association between entitlement and age, as well as longitudinal change across 6 years, we turn to the multi-group model to determine whether this negative relationship occurs from developmental change, or a generational difference. If it is a largely developmental effect, the slopes for each 5-year birth cohort from the multi-group model should fit well with the overall slope from the single-group model, and be negative (or potentially nonsignificant given the time frame). In contrast, if entitlement is increasing over time, the multi-group model should display positive slopes, indicating that entitlement has increased across 5 years (even as the single-group model may show a negative association between entitlement and age driven by cohort differences). If this occurs across all age cohorts, it would suggest that entitlement is on the rise generally; if this pattern is only found in younger cohorts, then it would suggest that entitlement is increasing among younger generations but not older generations. Finally, we also model separate trajectories of change in psychological entitlement for men and women. Although some research has found that gender does not moderate these changes (Grijalva et al., 2015), the existence of contrasting evidence (Donnellan et al., 2009; Twenge & Foster, 2010; Twenge et al., 2008) suggests it is worth investigating.
Method
Analyses were conducted for the 10,412 (62.5% women) participants who responded to at least three out of the six waves of the NZAVS. The NZAVS is an ongoing study that has been conducting an annual longitudinal panel survey of adult New Zealanders since 2009 (Time 1) through 2010 (Time 2), 2011 (Time 3), 2012 (Time 4), 2013 (Time 5), and 2014 (Time 6). We present a focused reanalysis of the data from Milojev and Sibley (2016). The items used to measure psychological entitlement make up part of the Milojev and Sibley measure of Honesty-Humility. However, Milojev and Sibley focused on tracking changes in Honesty-Humility, and Big Six personality more generally, whereas in the current research, we track change in psychological entitlement, separately for men and women.
The majority of the participants identified as New Zealand European (91.1%), whereas 15.5% of the sample identified as Māori, 4.1% identified as Pacific, and 4.7% identified as Asian. Socioeconomic status was calculated using the New Zealand (NZ) Deprivation index, a decile-based measure of deprivation in neighborhood units across the country with 1 representing the most affluent neighborhoods and 10 representing the most deprived (see Atkinson, Salmond, & Crampton, 2014). The mean score for the NZ Deprivation index in the sample was 4.86 (SD = 2.80). The mean age of the sample was 47.92 (SD = 14.91), and ages ranged from 13 to 94. For the purposes of estimating the Multi-Group Cohort-Sequential LGMs, participants were grouped into 5-year cohorts based on the year of their birth. These birth cohorts and their respective sample sizes are presented in Table 1.

Note. All correlations are significant at p < .001.
We tested for demographic differences between those that responded to at least three waves and those who did not respond to enough waves, and thus were excluded from the models. Looking at differences in the first wave, those who were excluded from the model for not responding in enough waves were younger (M = 43.49, SD = 14.70) than those included in the model (M = 47.91, SD = 14.91, t(19,801) = −25.24, p < .001). The excluded participants were also more likely to be living in less affluent areas (M = 5.06, SD = 2.85) than included participants (M = 4.86, SD = 2.79, t(11,030) = 3.60, p < .001), but there were no significant gender differences between excluded and included participants (62.0% female vs. 62.5%, respectively). Excluded participants were slightly higher in psychological entitlement (M = 2.81, SD = 1.43) than those included in the model (M = 2.67, SD = 1.36, t(10,276) = 5.34, p < .001). For a more detailed analysis of sample retention and bias associated with the longitudinal nature of the NZAVS, please refer to Satherley et al. (2015).
Materials
Psychological entitlement was measured by a short-form, two-item measure adapted from Campbell et al. (2004). These questions were embedded in the larger NZAVS questionnaire, among items assessing HEXACO or Big Six personality, all measured by a Likert-type scale from 1 (very inaccurate) to 7 (very accurate). The items used to measure entitlement were “[I] feel entitled to more of everything” and “[I] deserve more things in life.” The mean scale score was used in the analyses, and was constructed by calculating the mean of the two-item scale. Scale reliability estimates using Cronbach’s alpha were stable, ranging from .70 to .73 across the six points of assessment.
Analysis
As described earlier, we used two different but complementary estimations of Cohort-Sequential LGMs to assess change in levels of psychological entitlement across the lifespan (Milojev & Sibley, 2016; Preacher et al., 2008; Prinzie & Onghena, 2005). Firstly, we employed a Single-Group Cohort-Sequential LGM to estimate an overall growth trajectory for psychological entitlement between the ages of 19 to 74. Note that we included all participants in the analyses, including those younger than 18 and older than 74; however, we did not include them in the estimation of model-implied growth trajectories as these groups have small sample sizes which may be unreliable (Table 1). Secondly, we employed a Multi-Group Cohort-Sequential LGM for each 5-year birth cohort (Table 1) across the same age range. This second approach allows us to assess whether cohort effects are present in the estimated change trajectories in entitlement. The two types of models were estimated in MPlus 7.4 (Muthén & Muthén, 1998-2015) using maximum likelihood with robust estimation of standard errors (MLR).
To investigate gender differences in change in entitlement, we used a multi-group approach for both models, allowing for differences between men and women and estimating separate growth trajectories. We allowed the intercept and growth factors to differ for men and women; thus, enabling us to estimate separate rates of change in psychological entitlement across the lifespan. We constrained the variances for the growth factors to equality as we assume that the levels of individual differences in the rates of change are equal for men and women.
Single-group cohort-sequential LGM
Single-Group Cohort-Sequential LGMs were estimated based on scale means of entitlement at each of the six waves of annual assessments. The assessments correspond to the years 2009 (Time 1), 2010 (Time 2), 2011 (Time 3), 2012 (Time 4), 2013 (Time 5), and 2014 (Time 6). To estimate developmental change across the age range, participants’ ages were used as individual varying time indicators. A participant who was 19.50 years of age at their first response at Time 1 would be 20.50 years of age at the follow-up at Time 2, assuming that they completed each wave at a yearly interval. As participants rarely complete their responses exactly 1 year apart (i.e., 350 days for some participants, 400 days for others), participants’ exact ages (to two decimal places) were estimated at each time point, allowing for variation in age at assessment points. The responses from a participant who is 19.50 years of age at Time 1 will inform estimation of the growth curve in that area of the age range, whereas the response from someone who was 41.50 years of age at Time 1 will inform estimation of a later part of the growth curve. With the diverse range of age cohorts represented and the large number of participants of overlapping ages, a growth curve can be estimated representing change in entitlement over time from ages 19 to 74, with the different participants’ data informing different portions of the curve.
We modeled the rate of change in entitlement as a polynomial growth function including a linear, quadratic, and a cubic component. Even if these components were not significant, they were retained in the model to adjust for possible quadratic or cubic effects while estimating the linear component of the growth model. It is entirely possible that change over time follows a curvilinear pattern, so even if we were not yet able to statistically detect such patterns, they should be adjusted for. It also provides a more robust test of the linear component of the model.
A latent intercept (i) and a latent slope (s) were estimated based on the participants’ ages estimated as individually varying time indicators, using the TSCORE function in MPlus. Age was centered on the sample means for men and women. Quadratic (q) and cubic (c) slopes were also estimated. The latent intercept was estimated by fixing the six factor loadings (T1-T6) to 1. The latent intercept, thus, estimated the mean levels of psychological entitlement at the sample mean age, for both men and women. The latent slope was estimated based on individually varying indicators of participants’ age over time (T1-T6). Similarly, the quadratic and the cubic latent slope were estimated based on the quadratic and cubic functions of the individually varying indicators of participants’ age over time, respectively. Thus, the latent linear (s), quadratic (q), and cubic (c) slopes represent the linear or curvilinear change trajectory for entitlement across the available age range (19-74).
Multi-group cohort-sequential LGM
To estimate the Multi-Group Cohort-Sequential LGMs, the sample was organized into 12 sequential 5-year birth cohorts as presented in Table 1, for both men and women (n = 6,330). In congruence with the 5-year birth cohorts, the multi-group growth model was estimated based on the first five points of assessment (Time 1-Time 5). The 12th birth cohort (born in 1991 and later) was removed from the multi-group analyses due to small sample size (Table 1), leaving 11 5-year birth cohorts in the analysis (those born between 1940 and 1990). The multi-group models essentially estimate a different latent growth trajectory in psychological entitlement for each of these 11 birth cohorts. Although the NZAVS data allows for the use of 6-year birth cohorts, 5-year birth cohorts were used based on the common practice in the available literature on aging and normative change (e.g., Lucas & Donnellan, 2011; Milojev & Sibley, 2016).
As with the single-group model, the multi-group models were estimated based on the individually varying time indicators (i.e., date of response rather than age at time of response). Within these models a latent intercept (i) was estimated as in the single-group models, along with the latent slope (s), for each of the 5-year age cohorts seen in Table 1. The variances of the latent intercept and the latent slope, and the covariance between the intercept and slope were constrained to equality across the birth cohorts. Unlike the single-group models, only the linear slope was estimated in these models (refer to Milojev & Sibley, 2016, for Monte Carlo Simulations that estimate the power to detect varying effect sizes, i.e., the latent slope, given the varying sample sizes of the cohorts).
Each cohort LGM estimated change in psychological entitlement over 5 years of assessment for that cohort—that is, the 1986-1990 birth cohort represented change from 19 years of age to 24 years of age; the 1981-1985 cohort represented change from 24 years of age to 29 years of age, and so on. For each 5-year age cohort, the youngest age represented by that cohort was taken as an indicator of age in this framework. As the multi-group models spanned consecutive 5-year periods, the organization of birth cohorts into 5-year bands allowed us to sequentially organize the multiple LGMs. By employing this approach, the estimated levels of entitlement, the intercepts, and the latent change trajectories (i.e., the slopes) could be plotted across the adult lifespan (ages 19-74). This allows for simultaneous investigation of estimated cross-sectional cohort differences in the latent intercepts (i.e., the cohort differences in levels of entitlement at Time 1), the change trajectories in each cohort and the cohort differences in the rate of change (i.e., the latent slopes for each 5-year birth cohort), as well as the overall pattern of change in psychological entitlement that may be observed across the adult lifespan. Most importantly, this approach allows one to appreciate the age differences that are due to cohort differences, and those that are due to change over time. Sample Mplus syntax for the Single-Group and the Multi-Group Cohort-Sequential Growth Models can be found in Supplementary File 1.
Results
Descriptive statistics and bivariate correlations for psychological entitlement on the six assessment occasions are presented in Table 2. The mean of psychological entitlement at Time 1 was 2.67 on a scale of 1 to 7 (SD = 1.36). The means of entitlement at all time points (overall and separate for men and women) are presented in Table 2. The 1-year test–retest correlation for psychological entitlement was .63 (Time 1-Time 2), whereas the 5-year retest correlation was .59 (Time 1-Time 6).

Single-Group Cohort-Sequential LGMs
The parameter estimates for the Single-Group Cohort-Sequential LGMs estimating mean-level change in psychological entitlement across the six annual assessments for men and women are presented in Table 3. Figure 1 shows the estimated values of psychological entitlement across ages 19 to 74 for women, whereas Figure 2 presents the same estimated values for men. The Single-Group Cohort-Sequential LGMs are represented by the dark lines within each figure. For women, the estimated mean level of entitlement at the sample mean age (about 46 years of age; or 46.2, specifically) was 2.76 [2.72, 2.79]. The LGM indicated a negative linear trend from age 19 to age 74. For men, the estimated mean level of entitlement at the sample mean age (50.8 years of age, specifically) was 3.01 [2.96, 3.05]. The LGM indicated a curvilinear trend, with psychological entitlement initially getting higher across the age range, and then lowering after the mid-30s.

Multi-Group Cohort-Sequential Growth Models
The Multi-Group Cohort-Sequential LGMs are also presented in Figure 1 for women, and Figure 2 for men, with the estimates represented as the light lines within each age cohort. These models estimate mean-level change between the five annual assessments—from October, 2009 to July, 2013—within each of the 11 5-year birth cohorts for men and women. For women, the slopes are nonsignificant in almost all cohorts, indicating there is no within-cohort change over time. The exception is the 69-74 age cohort, where a positive, significant slope is shown (s = .066), indicating that the oldest age cohort reported increasing levels of psychological entitlement over 5 years. For men, we see a similar pattern with no within-cohort change over time observed in most age cohorts, but a significant positive slope in the 64-69 (s = .041) and 69-74 (s = .051) age-cohorts. For both men and women, the Multi-Group Cohort-Sequential LGM indicates an overall change trajectory that is subjectively comparable with that estimated by the Single-Group Cohort-Sequential modeling framework (represented as the darker line in Figures 1 and 2, and described in the previous section).
Cohort Effects
In the multi-group models, the use of 5-year birth cohorts with the five yearly assessments means there is an overlap between the estimated mean level of entitlement at the last assessment of one birth cohort, and the mean-level of entitlement for the same age at the first assessment point of the next cohort. For example, the LGM for the youngest cohort used in our models estimates change from age 19 at the first assessment to age 24 at the fifth and final assessment. The LGM for the next cohort estimates change across the five yearly assessments, from age 24 to age 29. Therefore, the two models each provide an estimate of mean-level entitlement at age 24, one from the 5-year latent change trajectory from age 19 to 24 (in 2013), and the second estimate from the initial level of the trait for those aged 24 to 29 (in 2009). The discrepancy between these two estimates can provide an indication of the difference between the model-implied value based on change over time, and the model-implied value based on cohort differences. That is, we can examine whether the change in entitlement seen across 5 years among 19-24 years olds puts them in the same place developmentally as a 24-year-old from 5 years before; if not, cohort differences may be at play.
The differences in estimated values of entitlement at Time 5 (2013) and the estimated values for the same age at Time 1 (2009) are presented in Figure 3 for both men and women, and it can be seen that many of the differences between the overlapping ages are nonsignificant, with confidence intervals that pass through 0. However, there are some significant differences. Among women, the results indicate that the 59-64 age cohort had higher estimated levels of entitlement than the 64-69 age cohort. Among men, differences can be observed where the 59-64 and 64-69 age cohorts have higher estimated levels of entitlement than their respective subsequent age cohorts. The differences described here are not ideal indicators of cohort effects, but they are a novel method for investigating cohort effects (see Milojev & Sibley, 2016) given the lack of longitudinal data collected across generations and consisting of participants of all ages.

We additionally conducted a formal test for cohort differences across the various change trajectories by running a set of models where the latent intercepts and the latent slopes were constrained to equality across each age cohort. We then compared the fit of these constrained models with the baseline models where the intercepts and slopes are free to vary across the age cohorts (Figures 1 and 2). The unconstrained models (Akaike information criteria [AIC] = 72,914.991, adjusted Bayesian information criteria [aBIC] = 73,100.908) provided a better fit than the constrained models (AIC = 80,075.476, aBIC = 80,093.353), as indicated by the smaller information criteria values (AIC and sample size aBIC) in the unconstrained models. These results suggest that cohorts are changing at different rates or in different directions (possibly reflecting the significant positive slopes in the oldest cohorts whereas the other cohorts show no change).
Discussion
The current research investigated change in psychological entitlement across the adult lifespan, using Cohort-Sequential LGMs and a large, heterogeneous longitudinal sample of adult New Zealanders. Overall, entitlement shows a steady negative trend across the ages 19 to 74. The multi-group model fits well with the single-group model, and there is little evidence of cohort differences. Younger birth cohorts (those defined as millennials) have higher levels of entitlement than older cohort birth cohorts, but their entitlement is not on the rise over time; instead, this may be the starting point of a lifelong decrease in entitlement as people age and mature.
The Single-Group Cohort-Sequential LGMs indicated a steady negative association between entitlement and age among women. Among men, a small initial positive trend in entitlement is observed from age 19 until the early 30s, at which point men also begin to show the negative trend across age cohorts. This fits with previous research demonstrating negative relationships between age and both entitlement and narcissism (Foster et al., 2003; Wilson & Sibley, 2011). With 6 years of data, we cannot yet be confident that entitlement decreases across the lifespan as people age; however, this is the “least contaminated” model; in addition to measuring entitlement across age, we also integrate longitudinal change across 6 years. Nonetheless, this does not rule out the possibility of cohort effects contributing to the overall negative slope. For further clarification, we turn to the Multi-Group Cohort-Sequential LGM.
The multi-group model was largely nonsignificant across the multiple birth cohorts, suggesting no change in entitlement over time. Significant positive slopes were found in the oldest age cohort (69-74) among women, and the two oldest cohorts (64-74) among men, suggesting that entitlement has increased among these ages, and only these ages, between 2009 and 2013. This may simply demonstrate a developmental pattern where those who have entered retirement feel that they have worked hard and deserve more at this point in their life. These results hold parallels to Marsh, Nagengast, and Morin’s (2012) “la dolce vita” effect where people become more self-focused and more self-content in their old age. There are no increases across time in any of the other birth cohorts, and in particular, there is no increase in entitlement across 5 years in those who fit in the millennial generation.
There are two interpretations for the largely nonsignificant multi-group model, whereas entitlement showed a negative trend across the lifespan in the single-group model. Firstly, if entitlement is not changing over time, then differences across the lifespan are largely driven by cohort effects (e.g., Milojev & Sibley, 2016). However, we tested for cohort differences in entitlement levels at select ages in 2009, and again in 2013, and there were very few differences. The only significant difference for women was at age 64, suggesting that women at age 64 in recent years have higher entitlement than women at age 64, 5 years prior. For men, there were significant positive differences at ages 64 and 69, similarly suggesting that entitlement is higher at those ages today than at the initial assessment in 2009. Younger cohorts having higher entitlement than their subsequent older cohort could contribute to the negative trend found across the lifespan. The evidence certainly suggests that some cohort differences are at play in older birth cohorts. However, given that these findings are limited to a few cohorts, they do not fully explain the negative association between entitlement and age, as the single-group model is informed by data from the entire age range. The second interpretation is developmental—if cohort effects cannot explain the negative association in full, then developmental change likely plays a role in the negative trend in entitlement across the lifespan, even though we may not (yet) detect decreases in entitlement across a period of 5 years; developmental changes are likely to be slow, incremental, and difficult to detect.
Entitlement has long been argued to be the domain of youth. Several researchers have put forward the view that entitlement is high among children, adolescents, and young adults, but that this is only temporary; entitlement should follow a decreasing developmental pattern as people grow, mature, and become committed to a variety of social roles such as work, marriage, and children (Arnett, 2010; Caspi et al., 2005; Kohut, 1971; Roberts & Wood, 2006). Roberts et al. (2010) argued that even when small differences are found across generations, they are unlikely to be larger or more important than the developmental changes. Our results support this view, with entitlement levels lowering across age cohorts, whereas there is limited evidence for cohort differences. Thus, when older generations look at younger generations and judge them to be more narcissistic than themselves, they may in fact be correct—at their current age. However, if entitlement follows a developmental pattern, these older generations may have been just as entitled when they were young. As Roberts et al. (2010) put it, “every generation is Generation Me . . . until they grow up” (p. 7).
It is difficult to compare our results directly with previous longitudinal studies, as the current research was conducted within New Zealand as opposed to the United States, with a representative heterogeneous population as opposed to college and high school students, and examines data from a shorter time span than previous research. However, despite these differences and our earlier discussion of New Zealand’s different cultural context, our results do fit well with studies from the United States that conclude there is no increase in entitlement over time (Donnellan et al., 2009; Grijalva et al., 2015; Roberts et al., 2010; Trzesniewski & Donnellan, 2010; Trzesniewski et al., 2008). The results from the multi-group model showed no significant change in entitlement within the same age ranges examined in previous studies. In addition, the cohort differences we found were minimal, and not widespread enough to fully explain the higher entitlement in younger cohorts relative to older cohorts.
Yet our results may not be inconsistent with previous research that found an increase, either (Stewart & Bernhardt, 2010; Twenge & Foster, 2008, 2010; Twenge et al., 2008). All previous data measuring change in narcissism over time was collected pre-2009, and therefore before the Global Financial Crisis (GFC) that affected many countries, New Zealand included (The Treasury, 2016). Recent research has suggested that those who were emerging adults during a recession, as evidenced by high unemployment rates for those aged 18-25, were likely to have lower narcissism than those who came of age at more prosperous times; this may even be an explanation for the rising narcissism levels measured over the past few decades (Bianchi, 2014; Twenge, 2013). As we have only measured entitlement post-GFC, we may have essentially “missed” the rise in narcissism among younger generations reported in U.S. samples (Twenge, 2013).
However, Bianchi (2014) noted that time did not appear to temper the effect of recessions on narcissism levels; that is, the conditions experienced in emerging adulthood set lower (or higher) narcissism levels for life. Thus, we would expect to see a “bump” in narcissism levels for those who were aged 18-25 before 2009—which may in fact be apparent among our results for men. Interestingly, further research has demonstrated that the effect reported by Bianchi (2014) may be limited to men, as men may place greater importance on economic achievement (Leckelt et al., 2016). Although these results taken together are still far from conclusive, they warrant further exploration, and the potential impact of the recession on the current research should not be underestimated. Nonetheless, although entitlement may or may not have increased before data collection, as of 2009, entitlement is not increasing among New Zealanders; it will be interesting to see whether post-2009 data in other contexts will show similar results going forward.
Gender Differences
Overall, men had higher mean levels of entitlement than women. In the single-group model, women show a steady negative trend in entitlement across the adult lifespan; however, men show an initial positive trend in entitlement that levels off in the early 30s and then begins the same decline across age cohorts. These results suggest young men may become increasingly entitled as they move from their teens through to young adulthood; however, without finding significant increases in entitlement over time we interpret these results with caution; this “bump” may also be related to prerecession cohort differences as discussed previously. There was also no evidence of women’s entitlement increasing to match men’s over time as has been suggested in previous research (Donnellan et al., 2009; Twenge & Foster, 2010; Twenge et al., 2008). If anything, signs point to a potential increase in entitlement in men over time as more of the slopes (although nonsignificant) were in a positive direction in the multi-group model among men as compared with women; something we aim to collect more data on, particularly given the smaller sample sizes for men.
Strengths, Limitations, and Future Directions
This longitudinal research expands upon previous research in the area by investigating change in entitlement across the adult lifespan, using a nationally representative heterogeneous sample. Extant research (e.g., Trzesniewski & Donnellan, 2010; Twenge et al., 2008) has focused on change in narcissism among high school and college students only. However, societal shifts that lead to increases in entitlement among younger generations may reasonably also affect older generations, so claims cannot be made comparing these generations unless change in entitlement is measured across a variety of ages; the current research only found increases among those aged more than 65. We note that if we only measured entitlement in young people, we might conclude that young men are increasing in entitlement over time; however, the data show that this trend reverses by the early 30s. Finally, examining change at all ages means we can incorporate views of entitlement and narcissism as personality traits that develop across the lifespan into the wider debate about change over time.
The current research is also the first to track change in entitlement longitudinally outside of the United States, an important first step as media discussion of rising narcissism reaches well beyond North America (e.g., Remes, 2016). Although New Zealand’s emphasis on a humble self-concept suggests there may be differences between countries in the development of narcissism over time, our results do not conflict much with previous research. Nonetheless, it must be cautioned that these results may not generalizable to other contexts, and to less individualistic contexts in particular (Foster et al., 2003). Although others have suggested that the rising levels of narcissism in the United States may have abated in post-GFC years (Twenge, 2013), our results may also be unique to the New Zealand context. For example, although we considered that the recession may have played a role in our results, supported by U,S. data (Bianchi, 2014), this effect did not replicate in Germany (Leckelt et al., 2016). Changes in entitlement are likely to be culturally bounded, and future research should focus on collecting longitudinal data in multiple contexts.
We noted earlier that the current research is a finer-grained analysis extending upon Milojev and Sibley’s (2016) research tracking change in Honesty-Humility (and Big Six personality more generally). Here, we utilized two of the items used to measure Honesty-Humility (reverse-coded) to measure entitlement. We did so because the four-item Honesty-Humility subscale employed by Milojev and Sibley (2016) incorporated facets of sincerity and fairness rather than being a pure measure of entitlement (Ashton & Lee, 2007). Specifically, that four-item measure was proposed by Sibley, Luyten, et al. (2011) and used two items adapted from the HEXACO (Ashton & Lee, 2009) and two items adapted from the PES (Campbell et al., 2004). Critically, we also expand upon prior research by estimating a multi-group model to analyze change for men and women separately. This provides a more focused analysis of potential gender differences in change in entitlement over time. These important distinctions between our analyses and research focus, and those of Milojev and Sibley, are illustrated in the different results found in the current research; whereas, the general trend is in the same direction, we find several gender differences and differences in both the significance and direction of the multi-group LGMs.
The Cohort-Sequential LGMs allow us to estimate both change over time, and change due to cohort differences. These models cannot, however, completely untangle cohort effects; we use 5 to 6 years of data to answer a question that, to be answered fully, requires a lifetime’s worth. The model allows us to estimate to what extent cohort effects may be affecting upon our estimates of change across age. The results show that, when tracking each cohorts change across time separately, they fit very neatly with the overall change across age, suggesting cohort differences are contributing minimally. However, we must recognize this approach as an approximation only at this current point in time; one we hope to improve upon in the future.
A natural drawback of a longitudinal sample is the opportunity for systematic attrition. We mentioned earlier that participants excluded from the analyses for not answering enough time points were slightly higher in entitlement than those included, which is not particularly surprising given the nature of entitlement. Satherley et al. (2015) found that Honesty-Humility is associated with higher sample retention within the NZAVS, indicating that those who are higher in entitlement may be more likely to dropout, which could potentially contribute to a negative trend in entitlement over time. In addition, those who aren’t included in the analyses are younger than those included. This could mean we are not tracking change in entitlement among those who are young and highly entitled; it may be that this population is the most likely to display increasing entitlement over time as entitlement may be self-sustaining (Campbell & Foster, 2007; Grubbs & Exline, 2016).
A limitation of this research is the short-form measure of entitlement we have used; a necessary trade-off of using a large-scale study with a nationally representative sample is the use of shorter measures. These two items serve as markers for entitlement, and the measure is capable of tracking meaningful change in individuals over time, although the effect may be stronger if a multi-item scale was used. However, it is important to note that short-form measures may be associated with Type I or Type II errors (Credé, Harms, Niehorster, & Gaye-Valentine, 2012; Kruyen, Emons, & Sijtsma, 2013). This measure of entitlement has been used in previous research within New Zealand multiple times (Stronge et al., 2016; Wilson & Sibley, 2011) and shows good reliability, but there appear to be some differences in the association between entitlement and age, and the NPI and age, for men in particular (Wilson & Sibley, 2011). We hope that these results illustrate the importance of expanding beyond a single age group when investigating development and cohort effects in future research, which may be able to utilize larger and more diverse measures.
In addition, this measure may be tapping into nonexploitative entitlement, suggested by Lessard, Greenberger, Chen, and Farruggia (2011) to be a form of entitlement where one believes they have a right to positive outcomes, but not a right to exploit others to get those outcomes. Therefore, when we report an increase in entitlement among those postretirement age, it likely reflects that people feel deserving of positive outcomes at that life stage, rather than a sudden shift toward exploitative behavior. Nonexploitative entitlement comes without the negative psychosocial consequences of exploitative entitlement, so the measure used in the current research may not be directly comparable with those in previous research. It is possible that there is a rise in exploitative entitlement over time, without a concurrent rise in nonexploitative entitlement (also see Crowe et al., 2016 for their emotionally stable/vulnerable conception of entitlement). However, we note that this seems unlikely given that nonexploitative entitlement is moderately correlated with exploitative entitlement, the PES, and the NPI (Lessard et al., 2011).
Finally, the lack of significant positive slopes in the multi-group model is, of course, not evidence that there is no increase in entitlement over time. We suggest we were unable to detect a decrease in entitlement within younger birth cohorts despite an overall negative trend across the lifespan, but it is possible that entitlement is in fact increasing over time, but slowly enough that more power is needed to detect the effect (e.g., among men aged 29-34; see Milojev & Sibley, 2016, for Monte Carlo simulations estimating the size of the effect that can be detected given the sample sizes in each birth cohort). However, those cohorts that do have significant slopes are not the largest in sample size, so if it is a matter of power to detect an effect, at the very least, the oldest cohorts are increasing in entitlement more rapidly than younger cohorts. Certainly, there is no evidence in these results for any kind of meaningful increase in entitlement among younger generations. Regardless, although 6 years of longitudinal data across the adult lifespan gives us an excellent first look, we do not expect change to be rapid and we are continuing to collect more annual waves of data.
Conclusion
We used a series of Cohort-Sequential LGMs to investigate change in psychological entitlement across the adult lifespan and over 6 years, for men and women. Our results indicate that psychological entitlement is steadily, negatively associated with age, but there is little evidence that entitlement is increasing across time. These results offer no support for the popular notion that entitlement is currently on the rise among “millennials” or younger generations—at least in the New Zealand context. Instead, they point to the idea that younger generations are naturally higher in entitlement than older generations as part of a developmental process. In time, as these current generations grow up and become less entitled, they may themselves become concerned by the entitled behavior they observe in future generations.
